Talk:Recording

When are two recordings the same

It would be good to mention when it's appropriate to merge recordings.

The following cases seem like they might need to be mentioned:

• Same audio data, but silence at beginning or end of recording
• Same audio data except for but fade in/out at beginning or end of recording
• Same audio data except for crossfade from another recording at beginning or end of recording
• Same audio data except for other stuff (e.g. talking) at beginning or end of recording
• Same audio data except for small part (e.g. fade) removed at beginning or end to shorten one
• Same audio data except for part removed from the middle to shorten one
• Same audio data except for short parts replaced with silence or another tone (e.g. a "clean" version of a song)
• Volume change but otherwise identical audio data
• Audio data remastered in a way that's a simple transformation from one recording to the other (e.g. re-equalized)
• Degradation of audio data in an analog copy of a recording (compare this to above)
• Audio data remastered in a way that requires access to more information (e.g. a particular instrument made louder)
• others?

Some discussion of this has already occurred on the mailing list, but it should be written up in documentation form and added to this wiki page. Dolphinling 06:32, 23 May 2011 (UTC)

Hi, is that a merge-list or a no-merge-list ? — a remastered release is same recordings ? PUID are not the same for the most (remasters) but ISRC are the same. It’s the same recording in the sense that it is not a re-recording. But is it the same MB recording ? I’d like it to be the same IMO. Jesus2099 14:34, 7 June 2011 (UTC)
